17 and 28,. entering a compartment 37' through the channel 38, the lower end of which is disposed below the level ofan overfiow, pipe 39, Withtheresult that a liquid seal is maintained at the lower end of the channel 38. It will be observed-that both the upper and lower surfaces of the rifile -plates are disposed to receive heat from eitherthe channel aor 0,.the hot gases-passing froinftlie apparatus through the passages lO! andj tl, and the vapors passing a from, the apparatus, at 42.

, It: is to'be understood that the construction illustrated in the accompanying drawings ismerely exemplary, and that the numberof riflie plates and: the number of preheating compartments or chambers, 8,. 9, etc.,.may. be multiplied to'any desired eX-. tent. There is a considerable degree of waste heat,--.available'inthe modern well pumping plants, and-the number ofirifile plates may be increased to the point where. all of the heating capacityof the'plant may be utilized in the-evaporationlprocess.

.Since the water passage bis water sealed by terminating; beneath the liquid level in compartment: 37, it follows that the evapration-of the liquidmay be carried out under sub-normal pressures,- ,byvirtue of which-the efficiency of. the apparatus. is furtherincreasech It will be observed that the rifile plates constitute a series of stairs with risers atthelower sides thereof, so that the liquid is-forcedtorun in a Wide shallow sheet over the. entire surface of the riflle plate and make the entire surface available 'for 'direct heattransfer toithe liquid by the hot gases passing; directly under and over these riflle plates- .The number. ofr'iflieplates which will be installed in any one apparatus will usually: be governed by the temperature of the outgoing. gases or products of combustiona By virtue of the apparatus herein Shownand described, the volumeof salt waten-whichinust. be disposed of maybe reducedto atrelatively small" quantity. of concentrated liquid which leaves the compartment 37 through the overflow pipe 39, and this-is insuch volume that it maybe readily disposed of without contamination of adja centilands, streams, or the like.

"It is to be understood that the invention is not limited to the particular arrangement shownjand' described, but that it includes within its purview whatever changes fairly comewithin'either the terms or. the spirit of th'eappended claims.
